What does this warning light mean (on an HP MP6 Laserjet printer)?

The symbol looks like a jagged lighting bolt and the orange light next to it is lit. The printer was working great earlier in the day but doesn't print now. The owner's manual was lost a long time ago (it's a big office and when I started, it was already lost) and the toll free 800 number for HP doesn't provide support. I already tried the online support and could not find the answer. Any suggestions would be appreciated. Thanks.What does this warning light mean (on an HP MP6 Laserjet printer)?
Either out of paper or a paper jam. Open the top cover, remove the toner and see if any paper is stuck. Also, pull out the paper drawer from the bottom and make sure there is no paper stuck.What does this warning light mean (on an HP MP6 Laserjet printer)?
the jagged sign means , you got a jammed paper or no toner /no paper, try to locate the stuck up paper on your feeder or exit roller on the fuser side, usually there is a small paper torn up left, when user pull out manually the jammed paper inside the printer.
